REPRESENTATIONS EXTREMALS

open access: yesPesquimat, 2014
In this work, we show the relation about a convex set with their extremes elements. We extended the Kein-Milman theorem in finite dimension for arbitrary convex set.

Decoding Hydrogel Porosity: Advancing the Structural Analysis of Hydrogels for Biomedical Applications

open access: yesAdvanced Healthcare Materials, EarlyView.
Porosity governs transport mechanics in hydrogels, yet characterization in its native state remains challenging. This work harnesses particle tracking to uncover three‐dimensional pore geometric features in polyethylene glycol hydrogels. Measurements in the native state reveal pores characteristics are comparable to those obtained by cryogenic scanning

Walrasian economy and some properties of convexly compact sets

open access: yesAnalele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2017
G. Žitković defined the notion of a convexly compact set in a topological space and, among other things, used it to give an extension of the Walrasian excess-demand theorem.

Engineering Anisotropic Mechanical Properties in Large‐Scale Fabricated Cartilage Constructs Using Microfiber Reinforcement

open access: yesAdvanced Healthcare Materials, EarlyView.
This study presents the development of large‐scale (15 cm2) cartilage constructs with anisotropic mechanical properties using melt electrowritten (MEW) microfiber reinforced cell‐laden gelatin methacryloyl (gelMA). These constructs mimic the mechanical behavior of native cartilage, providing a suitable environment for Articular Cartilage ...

Weakly convex and convex domination numbers [PDF]

open access: yesOpuscula Mathematica, 2004
Two new domination parameters for a connected graph \(G\): the weakly convex domination number of \(G\) and the convex domination number of \(G\) are introduced. Relations between these parameters and the other domination parameters are derived.

Extremal convex sets

open access: yesMonatshefte f�r Mathematik, 1983
Letf be an extended real valued function on the classK n of closed convex subsets of euclideann-dimensional space. A setK∈K n is said to bef-maximal if the conditionsK′∈K n ,K⊂K′,K≠K′ implyf(K)

3D Bioprinted Renal Constructs Using Kidney‐Specific ECM Bioink System on Kidney Regeneration

open access: yesAdvanced Healthcare Materials, EarlyView.
A kidney‐specific bioink derived from decellularized porcine kidney tissue supports the encapsulation, viability, and maturation of human primary kidney cells within 3D bioprinted constructs. In vivo, it also promotes the recruitment of host renal progenitor cells, collectively enhancing structural and functional regeneration of renal tissue.
